The CaviTAU® measurement unit
The intraoral ultrasound measurement unit contains an ultrasonic transmitter and an ultrasonic receiver e. g. “measurement unit”. The transmitter and receiver are in a fixed geometric position in relation to each other, so their position can be clearly defined. In CaviTAU®, the measurement unit should ideally be in a coplanar position. In order to provide a clearly defined, fixed geometric position, the two parts of the measurement unit are connected together. At least one arm is rotatable so that the two parts of the measurement unit form a gripper. The use of rigid arms makes the measurement unit extremely stable, and virtually eliminates the possibility of the receiver suffering a mechanical malfunction. The coplanarity of the transmitter and receiver is an essential attribute of the CaviTAU®’s design. When both parts of the measurement unit are in the optimal position, the gripper is slightly compressed so as to ensure acoustic conductivity between the measurement unit and the jawbone.
